Jameis Winston says confidence will be the key to Florida State's passing attack this season.

As the reigning Heisman Trophy-winner looks to build on the 25 of 40 completions for 370 yards and touchdown he had in the Seminoles' 37-31 season-opening victory against Oklahoma State, the quarterback says some of FSU's freshmen pass-catchers will be counted on to play a much bigger role moving forward.

Senior wide receiver Rashad Greene, who is the team's only returning starter at the position, caught 11 of Winston's 25 completions – including a game-clinching 50-yard touchdown pass – in the reigning national champion's six-point victory.

"I can't predict what a team's going to try to do, but of course, their main focus is going to be to try to stop Rashad and (senior tight end) Nick (O'Leary)," Winston said. "That's where those young guys are going to have to step up. That's why I said (the passing game is) a work in progress, because we've got to get those guys ready for the show."

Besides Greene, who played every snap of the game and finished with 203 yards and the team's lone TD catch against OSU, FSU's other wideouts combined for 103 yards on five catches.

"We got to get better at some things, and they gave us a lot of reads that left 80 [Greene] one-on-one," head coach Jimbo Fisher said. "We got the ball to him. People are going to start taking that away."

At the end of the night, Greene was targeted on 20 of Winston's 40 passing attempts.

Fisher says the star receiver was the primary option on just about half of the 11 receptions he had in FSU's opener. The fifth-year head coach, who is also the Seminoles' play caller, said Greene was Winston's second read on the rest of his receptions.

"(Greene) was open and he hit him," said sophomore wideout Levonte "Kermit" Whitfield, who had three catches for 30 yards in the game. "I'd do the same if I was Jameis."

Fifth-year senior Christian Green was on the field for almost every snap of the game and got off to a hot start. In just his fifth career start, and first since the 2011 season, the wideout came up with a pair of first-quarter catches including a 62-yard completion. But Green did not catch another pass in the game.

As the Seminoles look to get more players involved in the passing game this Saturday in their home-opener against The Citadel, Winston says he tries to instill confidence in the inexperienced bunch whenever he can.

"(Freshman) Ermon (Lane) had (come) to me one time. He had a practice where he dropped about three balls," Winston remembered. "He said, 'Man, do you still trust me?' I said, 'Of course I trust you.' I said, 'Because there's going to be one practice where I make three bad throws.'"

Green says little things like that go a long way.

"It gives you confidence because obviously that's the quarterback and he has a great arm and he's a great player," the fifth-year senior said. "Just coming back and hearing him say that, for the young guys and for all the receivers, it's like, 'Okay, I've just got to make sure I do my part.'"

"… He makes everybody feel comfortable."

Even though Lane and fellow freshman wideout Ja'Vonn Harrison did not play in FSU's opener, Winston says they will have to play a role moving forward, as will sophomore pass-catcher Jesus "Bobo" Wilson, who was suspended for the game, and freshman Travis Rudolph, who did not have a pass thrown his way against OSU.

But having studied Fisher's complex offense for more than four years, Green says it will take some time before the game slows down for FSU's trio of freshmen wideouts.

"It's going to take some time for everybody. Just because it's different," Green said. "It's a lot more reads and you have to be able to read the defense and look and see how they blitz."

In addition to Green showing his big-play ability early in the game against OSU, Whitfield's ability to read blitzes and adjust his routes, were positives Fisher came away with from the debut of the Seminoles' 2014 passing game.

"I wasn't totally disappointed in those receivers," he said. "We completed 25 balls. That's a lot of balls to receive in the game."

But some young players say they also worry about how their play will reflect on Winston, a season after the redshirt sophomore set a national freshman records for touchdown passes (40) and passing yards (4,057), in addition to leading the country with a pass efficiency rating of 184.8.

Winston says he tries to take that pressure off of his wide receivers by showing them that he too makes mistakes.

"I just continue to trust them and have confidence in them," Winston said. "After the game I was like, 'See guys, I threw two picks. That's not y'all's fault. That's why we need each other.' I just stress the fact that we need each other."
